WILLIAM L. BEALL, OF ALBION, MICHIGAN, ASSIGNOR T0 GALE MANUFACTURING COMPANY, OF' ALBION, MICHIGAN.

CULTIVATOR.

Specification of Letters Patent. Patented SQpt. 21, 1915;

Application led September 17, 1914. Serial No. 862,212.

To all whom t may concern Be it known that I, WILLIAM L. BEALL, citizen of the United States, residing at Albion, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

My invention relates to improvements in straddle row cultivators and more particularly to harrow attachments adapted to be used in connection therewith.

The object of my invention is to provide a harrow attachment for cultivators which may take the place of the ordinary gangs and be substituted therefor when desired.

A further object is to provide a harrow attachment which may be extended laterally to accommodate di'erent numbers of spring teeth, and which may be adjusted vertically and horizontally to change the angle of the teeth relative to the line of draft and also the position of the teeth relative to the surface of the ground over which the machine is traveling.

Vith these and other objects in view, my invention consists in the novel features hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which- Figure 1 is a top plan view of a cultivator equipped with my improved harrow attachment. Fig. 2 is a rear view of the same. Fig. 3 is a top plan view of a detail showing my improved harrow attachment extended to accommodate four spring teeth. Fig. 4 is a similar view showing the device contracted for use with three teeth. Fig. 5 is a section on line 5 5 of Fig. 3. Fig. 6 is a section on line 6-6 of Fig. 3.

My invention is shown as applied to the frame of a pivot axle cultivator such as shown in the U. S. Patent to William L. Beall, No. 654,125, dated July 24, 1900.

The harrow attachment, which is made the subject matter of the presentapplication is vsubstituted when desired for the gangs of the cultivator shown in said patent.

The cultivator shown in said patent comprises a main frame A, which consists of a Y series of bars a bolted or otherwise secured together and connected to the tongue a by bolts b. The rear ends of the bars of the frame are rigidly secured to the brackets B, having downwardly extending vertical shanks b upon which are swiveled the socket castings C which carry the axles c for the wheels D and foot levers E for guiding machine. Each of the sockets C has a rigidly connected forwardly extending arm e which arms are connected for joint movement by a bar F. The construction just described permits the guiding of the machine by pressinlT on the foot levers E. An operators seat C; is also provided upon said frame.

The forward portion of the frame A has rigidly connected thereto by U-bolts H, an arch, I, upon the lower horizontal ends of which are loosely mounted sleeves K and brackets L are rigidly secured to said sleeves. To the brackets are pivotally connected by bolts Z my improved short beams M. It will he notedl that the pivotal connections between the beams and the arch allow the beams to be swung in either a vertical or horizontal direction.

The rear ends of the beams M terminate in brackets N to which are swiveled the plow carrying plates C. Arms P extend laterally from the brackets L and are pivotally connected to links 79, the other ends rof the links being pivotally connected to the carrying plates C. means for adjusting their length for the purpose of changing the position of the'- plows, hereinafter described, relative to the line of draft and said adjusting means consist in forming the links in two parts, a screwy threaded portion 79 and a yoke p2. The screw portions p pass through apertures (not shown) in the yokes 792 and are secured by means of nuts p3 which are also used to change the length ofthe links.

Each of the carrying plates O is provided with-an aperture C and a curved slot O2, the edges of the slot being corrugated as shown at C3. Bolts R provided with nuts pass through plow frames S, hereinafter described, and through the apertures- O and slot O2 tosecure said plates and said frames together. IIlie plane of the plow frames S may be varied relative to the surface of the ground by loosening the bolts R and swinging the frames on the bolts which pass through the apertures O', the curved slot permitting this to a certain extent. When Vthe middle one of which is used when1 the vmoving the plows laterally simultaneously the frames have been turned to the desired pwardly. As the bars are brought together position, the nuts on the bolts R are tight t the bolts R and 6 travel in the slots 4a and ened, clamping the parts securely togethe fi 5a until the outer ends ci' said slots abut andl this is additionally insured by the ,useof corrugated collars under the nuts ot' the""`"" bolts which pass through the slots 02 which engage the corrugations O3. Y ,iv

The plow frames S each comprise a mainV fiat plate 1, a main angle bar 3 and two subsidiary angle bars #l and 5, which are clamped between the plate l and angle bar 3 and extend beyond the ends of said plate and bar. `l`he bolts l pass through aper-y tures la in the plate l, slots Ll@ and 5fL in the bars l and 5 and apertures 3 in the bar 3, and secure said plate and bars together and to the carrying plate O. Bolts 6 pass through apertures :1b in the plate 1 and through the slots in said bars' and 5v to y additionally and adj ustably secure said parts y together. rl`he bar 3 is provided in its'rhorizvontal portion with three equidi'stantly spaced apertures 3b, the end ones of whichy are adaptedl to be used when theV plow frames are extended as shown in Fig. 3, and

bolts are'tightened. @ne of the bolts 9 is then passed upwardly through the center one of the apertures 3b of the plate 3, and between notches 3C provided on the inner .ends of the bars l and 5, the two notches when brought together forming an aperture equal in area tothe apertures 3b. vsplate 7 and tooth 8 are then placed on said bolt and a nut applied, thus forming the construction shown in Fig. il.

The abovedescription sets forth my preferred construction for obtaining the results tion, but it is obvious that the details may be modified without departing from the spirit of my invention. I

What l claim. and desire to secure by Letters Patent is 1*' frame', of a harrow attachment comprising beams," extensible plow frames provided with teeth, Vand means vfor adjusting said plow `frames relative to said beams,

2. The combination with a vcultivator frame, of a harrow attachment comprising a plurality or"` beams pivotally connected to said cultivator Eframe for vertical and hori- Zontal movement, carrying plates pivotally connected to said beams, means for adjusting the angle oi'A the carrying plates relative to the beams, plow frames provided'with teeth andmeans provided between the plow iframes and-carrying plates for adjusting frames are contracted as shown in Fig. l. Alining plates 7 and spring plow teeth S arey secured to the bars e and 5 by bolts 9 and each uof the plates 7 is provided with downwardly depending flanges 7 a to engage the edges of the plates and 5, and with upwardly eXtending .ridges 7" to engage the side edges yoli' the plow teeth to prevent the same from moving laterally. The bolts 9 also secure plates 10 to the plow frames and said plates have loops l0a which are connected up with the means (not completely shown) for elevating the plow frames. .Oblong apertures 10b 'are' also provided in said plates l0, through which pass downwardly extending arms 11. These downwardly eX- tending arms l1 are secured at their upper ends to sleeves l2, which are provided upon the bar F and they are for the purpose of the surface of the ground. n
